Market volatility is an inevitable reality of equity investing, but disciplined portfolio managers convert periodic downturns into permanent tax savings through systematic tax-loss harvesting.
When an ETF or stock drops below its purchase cost basis, selling the position locks in a capital loss. This realized loss can dollar-for-dollar cancel out capital gains realized anywhere in the investor's taxable accounts, with up to $3,000 in excess losses offsetting ordinary wages.
Avoiding the IRS Wash-Sale Rule
The IRS wash-sale rule prohibits repurchasing a 'substantially identical' security within 30 days before or after the sale. Astute investors maintain market exposure by instantly rotating sale proceeds into a highly correlated substitute index fund, preserving long-term compounding trajectory while capturing the tax deduction.
